Title: Method and apparatus for shrink wrapping an annular article
IPC: B29C63/06
Filed: 1979-05-17
Abstract: A method of covering the outer cylindrical surface and the two ring- shaped sides of an annular article with a heat-shrunk plastics film comprises a first stage, carried out at ambient temperature, of covering said cylindrical surface with heat- shrinkable film which projects laterally beyond said surface, and a second stage of heating from above successive portions of the film to its shrink temperature while rotating the film covered article about an axis (11). During the or each revolution of the article successive parts of each laterally projecting film portion moved below a heater are urged by shrinkage forces and gravity towards a respective side of the article. Gravity subsequently urges said successive parts away from said side but this is of no significance since said parts are below their shrinkage temperature during this time. An apparatus for performing the method comprises a rotatable spindle (8) for carrying the annular article to two stations where respective stages of the method are carried out. <IMAGE>

Title: Folding agricultural implements
IPC: A01B73/04
Filed: 1980-06-04
Abstract: The invention relates to a latching/unlatching assembly in agricultural equipment having at least two laterally arranged sections (10, 20) e.g. harrow or roller sections, which are swingable towards each other. Through the action of operating apparatus (40) a releasable catch device (30) not only automatically locks the sections together when they are in a retracted position but also automatically releases the catch device when the sections (10, 20) are swung outwardly. This is achieved by the operating apparatus (40) being connected to one section (20) with the aid of connecting means (38), which latter is movable between two stops (42, 43). Thus, in the first stop position, the catch device (30) assumes a locking position when the sections (10, 20) are swung towards each other, while in the second stop position, the connecting means (38) automatically moves the catch device (30) from its locking position to free said sections (10, 20) for swinging movement away from each other, this swinging movement being provided by the operating apparatus (40). The catch comprises a spring-loaded rod (31) whose end (32) is moved behind a detent (13) by an arm (37) attached to the rod and pivoted to the connecting means (38). <IMAGE>

Title: M.T.I. radar processor
IPC: G01S13/526
Filed: 1981-04-08
Abstract: For moving target indication, in a three-pulse system, the radar returns to a rotating antenna 64 are detected (74), range sampled (76) and converted (80) to digital words in both in-phase (I) 70 and quadrature (Q) filters 110. The digital words following first and second pulses are stored in stores 82, 84 and fed with the words following the third pulse to three velocity filters 26, 28, 30 with different patterns of weighting coefficients for A, B and C channels corresponding to the three pulses. Filter 26 producing a signal F1 corresponds to a conventional MTI filter. The other filters for F2 and F3 have orthogonal weights so that noise is uncorrelated. The I and QF1signals are squared (112) and summed (114) with conversion to logarithms to provide an output F1 signal fed to video output circuits 116, the F2 and F3 signals being similarly treated. F1 also updates a leaky bucket clutter map store 32 whose contents are subtracted above zero, 20 dB and 40 dB thresholds respectively from the F1, F2 and F3 signals before these are combined and converted back to a video output for a PPI display 54. <IMAGE>

Title: Gauge changing apparatus
IPC: D04B37/00
Filed: 1981-07-24
Abstract: An apparatus or transferring knitted fabric from needles of a first knitting gauge to needles of a second knitting gauge comprises a row of parallel, elongate points each mounted on a respective flexible band 60, the bands being secured at each end to a movable frame 36.

Title: Apparatus for Screening a Glasshouse
IPC: A01G9/22
Filed: 1981-11-26
Abstract: Apparatus for thermally-screening a glass house comprises a fixed channel member 16 having upper and lower flanges 18 and 19, between which may be received a movable channel member 29 slidably supported by upper wires 28 and lower wires 24. A flexible fabric screen having a metallic coating is attached to the webs of the members 16 and 29 by clips 22, such that movement of member 29 away from member 16 will draw out the screen. Conversely, movement of member 29 towards and eventually into fixed member 16 bunches up the flexible screen and then compresses the screen material into the smallest possible volume. When drawn out the screen is supported by the lower wires 24; on being folded away the screen is constrained to enter both channel members 16 and 29 by the upper and lower wires 28 and 24. The movable member 29 is attached to a driving cord 26 by means of a clamp 35 which normally prevents relative movement between the cord 26 and movable member 29 but which allows slippage to occur therebetween in the event of the movable member 29 jamming. <IMAGE>

Title: Nuclear Magnetic Resonance Imaging
IPC: A61B5/055
Filed: 1982-01-08
Abstract: Method and apparatus for producing an N.M.R. picture of a plane through an object by isolating the plane using an oscillating gradient and interrogating the plane using a rotating gradient and a multiplicity of R.F. pulses which are averaged over a defined period to produce an average response which is used to product the N.M.R. picture. A set of N.M.R. signals from which may be derived by known techniques the image of a selected plane through an object is obtained by subjecting the object to a high constant magnetic field, to an oscillating magnetic field having a gradient and having zero intensity at (defining) the selected plane, and to a field gradient the direction of which gradient (in the selected plane) is rotatable such that there is a unique point in the plane when the total field is invariant; for each of a plurality of distances of the rotatable gradient the object interrogated by at least one R.F. pulse. Preferably, as shown, the gradient is rotated by increments, at each of which an initial R.F. pulse sequence saturates all the object save the selected plane; the latter is then interrogated 200-300 times with exciting R.F. pulses and the average N.M.R. response obtained. Alternatively the gradient direction may rotate continuously, again with a large number of interrogating R.F. pulses per unit of rotation for providing an averaged N.M.R. response. Three windings may be used to provide orthogonal field gradients, any one being selected for AC excitation for the oscillating field, and the other two being fed with sinusoidally and cosinusoidally varying current for the rotating gradient. <IMAGE>

In a second step the uppermost sheet (1) in the stack is drawn off and the folding is completed, whereby the sheet, seen in cross-section, is folded up in zigzag pattern, with the flap (6) projecting outward. Thereafter the folded-up sheet according to a third step is inserted into said cover, whereafter the second and the third step are repeated until as many sheets (1) as desired strips in a book have been inserted into the cover (7), whereby thus a number of folded-up sheets (1) are inserted in a row of as many coherent covers (7). In a fourth step the cover (7) for each book is stapled together with the flaps (6) inserted into the cover, whereafter in a fifth step the row of coherent books are broken apart along the break perforations (13 and, respectively, 5) in the cover (7) and sheets (1). <IMAGE>
